ABSTRACT:
A cooling system for a vessel, such as a blast furnace, containing hot gas. The cooling system comprises a large number of cooling circuits each having one or more cooling members extending inwardly into the blast furnace walls. At the downstream end of each cooling circuit is a device which indicates when a cooling member in that circuit has a leak. Each leak detecting device comprises a container normally filled with water which is displaced from the container by gas from the blast furnace when there is a leak in a cooling member. The displacement of the water by the gas is visually displayed or generates a signal to indicate the occurrence of a leak.
